Morphea and lichen sclerosus et atrophicus. Clinical and histopathologic studies in patients with combined features.

Ten patients with skin lesions clinically consistent with morphea and lichen sclerosus et atrophicus were studied. In all cases, histopathologic changes of both morphea and lichen sclerosus et atrophicus were also present. The coexistence of morphea and lichen sclerosus et atrophicus in the same patient suggests that these lesions represent a spectrum which may reflect similar etiologic events or closely related pathologic processes in these two diseases.
